[Pythoncard-users] Controlling pythoncard app initial screen position

I'm trying to get my app to always start in the same position each
time I run it, instead of some random position.
However, the method I've used in other programs doesn't seem to apply
in Pythoncard


I get the screen width & screen height as follows

 from win32api import GetSystemMetrics
        SM_CXSCREEN = 0
        SM_CYSCREEN = 1

        #self.ScreenWidth  = GetSystemMetrics (SM_CXSCREEN)
        #self.ScreenHeight = GetSystemMetrics (SM_CYSCREEN)

then

self.position[0] = (self.ScreenWidth - self.size[0]) / 2
self.position[1] = (self.ScreenHeight - self.size[1]) / 2


However, Pythoncard seems ot be overwriting the values I put in self.position.

Would someone show me a better way to center a pythoncard app on startup?


Merry Christmas Everyone!
